コストダウンが図れるようになる。After this compression, the side lid 2 is tilted outward and opened, and the upper mold 5 is closed on the upper end of the lower mold 1 to maintain the compressed state of the fiber base material 3. The compressor 6 is then raised and retracted to the state shown in FIG. 5. By heating or steam heating in this state, the fibrous binder 3b is melted and attached to the intertwined points of the fibers 3a. After the attached binder is cooled and hardened, it is removed from the mold. In this way, a cushion material molded into a predetermined shape is obtained. In other words, the filling of the fiber base material 3 into a cedar mold, pressurization, heating, and other shaping processes can be automated without relying on manual labor, and productivity can be greatly improved and costs reduced.

ても良い。In the above example, if the degree of mutual entanglement of the cotton ball-like fiber base materials 3 is weak with only the fibrous binder 3b, a liquid binder is applied around the cotton ball-like fiber base materials 3 in advance. It may be applied and then filled by blowing. Furthermore, as described above, instead of using the fibrous binder 3b, the cotton ball-shaped fiber base material 3 may be impregnated with a liquid binder in advance.

When the cotton filling device 4 automatically blows and packs a large number of cotton ball-like fiber base materials 3 into the lower mold 1 together with air, the cotton ball-like fiber base materials 3' (Fig. (filled in black) and an unhardened cotton ball-like fiber base material 3 are prepared. Then, while the unhardened cotton ball-like fiber base material 3 is being blown into the mold by the cotton filling device 4, the cotton filling device 4 is controlled, and the cotton ball-like fiber base material 3' that has not been solidified is is locally blown and filled into the parts of the mold where it is necessary to weaken the hardness.

ョン材でも簡単に戊形できるようになる。First, in the example shown in FIG. 6, in the manufacturing method of the cushion material of the above embodiment, a cotton ball-shaped fiber base material 3 is placed in one pile of a lower die made of punching metal from above using an air flow by a cotton filling device 4. When blowing in or 3', suck from the opposite side. That is, a suction blower device 7 with a hood 7a that covers the lower surface of the lower mold 1 is set below the lower mold 1. Then, the blower 7b provided midway through the exhaust port of the suction blower device 7 is operated to suck the fiber base materials 3 and 3' filled into the mold downward. As a result, the cotton ball-like fiber base materials 3 and 3' are successively attracted and accumulated on the inner surface of the lower mold 1, and the cotton ball-like fiber base materials 3 and 3' can be filled into the mold more quickly and accurately. This allows for even greater productivity improvements and cost reductions, as well as
The cotton-like base material conforms to the inner surface of the mold, resulting in a complex shape. Even cushioning materials can be easily shaped.
第７図に示す例は、前述同様に綿充填装置４で綿玉状の
繊維基１イ３を下型１に所定量詰め込む。In the example shown in FIG. 7, a predetermined amount of cotton ball-like fiber bases 1 and 3 are stuffed into the lower mold 1 using the cotton filling device 4 as described above.
